Basic properties of refined, bleached and deodorized soybean oil-butanol blends

► We analyze basic properties of RBD soybean oil-butanol mixtures. ► Mixing rules are established for relative density, viscosity, and HHV. ► An exponential relationship is found for viscosity based on composition. ► Increasing butanol composition improves the PP, CFPP and CP. ► Butanol has the greatest influence on the CFPP and CP at mixture compositions <25%.
